VSOP87 Rust implementation
This library implements the VSOP87 algorithm in Rust. The use can be seen in the documentation. The library currently is divided in one module per VSOP87 version implementation. The implemented ones are basic VSOP87 algorithm and VSOP87A. The rest of the algorithms (VSOP87B, VSOP87C, VSOP87D and VSOP87E) will be implemented in the future.
